keepalived ??

[texerasmo]

Cioa a tutti.
Allora io ho questo scenario

nodo1 Apache + keeplived 192.168.0.143
nodi2 Apache 192.168.0.149



file di configurazione
keeplived.conf

! Configuration File for keepalived

i file virual host
httpd.conf del nodo1
<VirtualHost 192.168.0.143:80>

ServerAdmin www.balance.dev
DocumentRoot /home/mino/
ServerName www.balance.dev
ErrorLog /var/log/sneto/error_log
CustomLog /var/log/sneto/access_log common
</VirtualHost>

httpd.conf del nodo2
<VirtualHost 192.168.0.149:80>

ServerAdmin www.balance.dev
DocumentRoot /home/mino/
ServerName www.balance.dev
ErrorLog /var/log/sneto/error_log
CustomLog /var/log/sneto/access_log common
</VirtualHost>


ora mi dovrei aspettare un cosa del genere
le chiamate al sito www.balance.dev dovrebbere essere dirottate sia sul nodo1 che nodo2,oppure in caso un apache va giù le chiamate vengono dirottate sul nodo attivo.

nodo1 keeplived on
nodo1 apache on
nodo2 apache on

ovviamente non funziona

Questi sono i valori dopo il ./configure
secondo voi quel no determina il funzionamento?

cmq ora ho abilitato LVS infatti nella compilazione ho questo messaggio ora

il mio file di configurazione è fatto in uesto modo

}

il test che sto facendo è il seguente

nel dns configuro il sito www.balance.dev sull'ip 192.168.0.143
